PUSHER FOB MANURE-SPRE ADERS.

Patented Aug. 6, 1907.

Application filed February 28, 1907. Serial No. 359,'7Ol1 To all whom il may concern:

Be it known that I, DALToN K. WILSON, a citizen ol the United States of America, and a resident of Gladbrook, Tama county, Iowa, have invented certain new and useful Improvements in Pushers for lilanure-Spreaders, of which the following is a specification.

My invention relates to improvements in manurespreaders, and the object of my improvement is to provide a pusher which will become automatically detached from the apron of the spreader when it has arrived at its rearward limit of movement.

This object I have accomplished by the means 'whichpare hereinafter described and claimed, and

which are illustrated in the accompanying drawings, in Which- Figure l is a plan view of the bed of a manure-spreader with my detachable pusher in sita; Fig. 2 is a side elevation of the same, and Fig. 3 is a perspective view ofsaid pusher.

Similar letters refer to similar parts throughout the -several views.

My improved detachable pusher is primarily intended i'or use on maniue-sprcaders having an endless apron, but if desired it can be used on those machines which possess return aprons.

I have illustrated a portion ol' the body of a manure spreader, consisting of a bottom h, side-boards g, beater-drum k, and an endless apron consisting of slats f having upturned flanges l attached to the endless chains e. Y ,i

My improved pusher consists of a curved board a, which is snpported on angle-irons b, the upper 1nembers of which are secured to said board at its ends, and whose lower membersare horizontal and arranged to act as guides to slide over the upper surface of the bottom h outside ol said apron. I have attached to the lower edge of said board downwardly projecting bars c, which only extend downward suiiicielitly to engage the rearward surf-acc of one of the slat-llanges Z when the said pusher has been placed in the position illustrated on said apron. The bracket arms d are secured to the two upper corners ol' the board a, an'd are thon bent horizontally forward, und then laterally outward suilicieutly to ride upon the upper' edges el the side-boards y. The ordinary form of supplemenrearward movement oi the apron will carry said pusher backward horizontally until the bracket arms d arrive at the sloping edges of the boards i. The further movement of said apron drives the laterally extending portions of said arms up the slope of the forward edges of said boards t', causing the bars c to lift off from said apron to clear the flanges l of the slats f. The pusher may then be lifted by hand from the rear part of the wagon-box and returned to the forward portion of the box and then deposited on the apron in a similar manner to be again returned.

This type of detachable pusher maybe arranged to deviate slightly in its details of construction in order to conform to the requirements of adjustment to different types of manure-spreaders, without deviating in principle from this invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. A device of the character described, consisting of a plate, such plate having interni projections from its ends adapted to serve as slide-hangers, and. projections from its lower edge extending :1 desired distance downueird.

2. A device of the character described, consisting of n plate having lateral projections from its ends adapted to serve as slide-hangers, projections extending a desired distance downward from its lower edge, :1nd guide-projections extending horizontally from its lowcriedge.

I H. A device of the character described, consisting of f1 pluie havingr engaging means at its lower edge, and provided with guiding.,r means for maintaining it in a vertical position.

4. In n manure spreader, in combination, a wagon-body having :L rearwardly movable apron therein, and n det-ich- :lhlc pusher-plute provided with means for removably engaging' it to said apron. v

in n rn:lnure-spremler, in combination. a wagon-body having a longitudinally movable apron therein, a detachuhle pusher-plaie adapted to engage said apron, -and means lt-r detaching said pusher-plate from said apron when the said pluie has arrived at its rearward limit of movement,

Signed at Waterloo, Iowa, this lith day of Feb. 1907.
